RAIL-JOINT CHAIR.

Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed February 11, 1916. Serial No. 77,596.

To all whom it may concern:

Be it known that I, WILLIAM A. PINOK- NEY, a citizen of the United States, residing at Stanton, in the county of Montcalm and State of Michigan, have invented certain new and useful Improvements in Rail-Joint Chairs, of which the following is a specification.

This invention relates to improvements in rail joint chairs, one object of the invention being the provision of a chair that will properly connect and support a rail joint, and at the same time allow the necessary expansion and contraction at the joint due to changes in temperature.

A further object of this invention is the provision of a rail joint chair, which is simple, durable and inexpensive in construction, and which is thoroughly eflicient and practical in use.

In the accompanying drawings :Figure 1 is a perspective view of the complete chair with the rails connected thereby. Fig. 2 is a perspective view of one member of the chair. Fig. 3 is a similar view of the other member. Fig. 4, is a fragmentary vertical longitudinal sectional view of the chair. Figs. 5 and 6 are detail views.

Referring to the drawings, the numeral 6 designates the two rails that are to be connected by the chair 7.

This chair consists of the two members 8 and 9, the member 8, being cast or formed integral to provide the base flange 10, the solid tread forming and rail continuity member or block 11, and the rail web embracing portion 12. Thus the ends of the rails fit upon the base so that the edges of the bases thereof fit into the recesses 13, with the extreme ends abutting at either side of the block 11. The faces of the lug and base extend slightly beyond the center of the rails bases and treads, to cooperate with the small base receiving recesses 14 of the member 9. This member 9, is also provided with the tread and rail continuity member 15, and the rail web engaging portions 16, the locking bolts 17 being passed through the members 11 and 15 of both members to copies or this patent may be obtained for hold them together at the point of engagement between the ends of the rails. Thus the rails do not have to be pierced to receive the usual bolts that attach the fish plates and other usual connections in place.

To further assist in holding the bases of the members 8 and 9 from spreading the clamping members 18 are employed the same being slidably mounted to fit upon the members and thus hold them at their bases beyond the members 11 and 15 in place.

By this construction of chair the rails are permitted the necessary contraction and expansion, and by reason of the fact that the chairs are so easily and quickly assembled, the present device can be quickly placed in proper position.

By providing the solid portions 8 and 15 between the meeting ends of the two rails, no wear at the meeting ends is occasioned, thus this chair not only supports the ends of the rails but prevents the ends from rounding ofl, as in the case where the present fish plates are employed. The ends of the rails are also held against depression, due to this form of chair and the solid central wheel receiving portion thereof.

Although herein has been described and illustrated a preferred form of my invention, it is apparent that various changes can be made and still be within the scope of what is claimed.

lVhat I claim, as new, is

A rail joint chair for clamping the ends of two rails together, and including two similar shaped members, each of which is provided with solid tread forming and transverse movement limiting portions, such portions being provided with bolt receiving openings, oppositely disposed portions having recesses to receive the base and web and also the underside of the tread of the rail ends, bolts passing through the openings to clamp the members together upon the rail ends, and two clamping plates fitting upon the bases of the two members to hold them from separating.

In testimony whereof I aflix my signature.

WILLIAM A. PINCKNEY.
